IPC: C03B8/04
Filed: 1992-02-10
Abstract: PURPOSE:To provide a method for producing an optical fiber preform capable of precisely controlling the ratio between the core diameter and the clad diameter of the optical fiber preform. CONSTITUTION:The detection value Wa of a weight detector on the passage of a burner through an end A of the effective part 4a of an optical fiber preform substrate and the detection value Wb of the weight detector through the other end B are determined. The determined values are subjected to a subtraction of (Wb-Wa) to determine the deposition amount of glass fine particles deposited between the one end A of the effective part 4a of the optical fiber preform substrate and the other B with the burner. The glass fine particles are deposited until the value reaches a desired value.

Filed: 1981-02-23
Abstract: PURPOSE:To make the discrimination of content of audio signals of a plurality of channels easy, by specifying the frequency of a pilot signal to almost (2N+ 1)/2 times the video signal horizontal scanning frequency in frequency multiplexing. CONSTITUTION:The frequency of a pilot signal used for the discrimination of content of a plurality of chnnel audio signals is restricted to almost (2N+1)/ 2 times the horizontal synchronizing signal to avoid the cross modulation noise with an FM modulation video signal. That is, a difference signal of stereo audio or a sub-audio signal is inputted from an input terminal 2, and after a pilot signal in different frequency is added at an adder 10 according to stereo audio and double audio, the result is modulated in an FM modulator 4. The pilot signal is a signal formed from a horizontal synchronizing signal in frequency fH from an input terminal 11 at a 2.5 multiplication circuit 13 and a 3.5 multiplication circuit 14. Thus, the reproduced S/N of the pilot signal is increased and the discrimination of content of a plurality of channel audio signals is made easy.

Title: Magnetic recording medium
Inventor: NOCHI KIDAI
IPC: G11B5/64
Filed: 1981-02-20
Abstract: PURPOSE:To improve corrosion of a magnetic recording medium easily, by laminating a ferromagnetic thin film on a plastic film via a corrosion-resistant thin film. CONSTITUTION:A corrosion-resistant thin film, preferably an alpha-Fe2-deltaO3 (0<=delta<=1) thin film 4 is formed on the surface 3 of a plastic film 2, and a ferromagnetic thin film 1 is formed on this thin film 4. The thin film 4 is a film where Fe is evaporated and laminated by controlling the temperature of the plastic film 2 and the amount of oxygen, the vapor deposition speed in oxygen atmosphere. Even if water molecules already incorporated in the plastic film 2 appear on the surface 3 of the plastic film 2, since the chemically very stable thin film 4 is formed on the surface 3, the movement of water molecules to the ferromagnetic thin film 1 is interrupted, consequently the corrosion of the ferromagnetic thin film can be reduced.

Filed: 1990-02-06
Abstract: PURPOSE:To reduce not only the effect of the humidity in a measuring light path but also the fluctuation of a measured moisture value to the fluctuation of humidity by irradiating an object to be measured with respective reference and measuring wavelength infrared rays and measuring moisture on the basis of the quantities of reflection of the respective rays. CONSTITUTION:The wavelengths of reference wavelength infrared rays hardly changing in the quantity of absorption by the moisture content of an object to be measured is set to a constant wavelength region on the side of the wavelength contained in the absorbing band of water in the vicinity of 3mum and longer than that of the absorbing band of steam in the vicinity of 2.7mum. The wavelength of measuring wavelength infrared rays changing in the quantity of absorption by the moisture content of the object to be measured is set to a fixed wavelength region shorter than the wavelength of the absorbing band of steam in the vicinity of 2.7mum and becoming longer than the wavelength of the absorbing band of water in the vicinity of 2mum. By this setting, measuring wavelength infrared rays are easily absorbed by water but hardly absorbed by steam and reference wavelength infrared rays are hardly absorbed by both steam and water. Therefore, both of them hardly receive the effect of steam and the moisture content of the object to be measured can be measured on the basis of the difference between the quantities of the reflected lights of both of them.
